They were added to include/linux/compiler.h in 2.4.10, but this doesn't 
seem to be included by any of the other linux/*.h files until later on:

   include/linux/kernel.h 2.4.19 includes linux/compiler.h
   include/linux/init.h 2.4.26 includes linux/compiler.h
   include/linux/module.h 2.4.27 includes linux/compiler.h
   include/linux/string.h 2.4.28 includes linux/compiler.h

The include/linux/compiler.h file itself did not appear until 2.4.4.

I have attached a patch against CVS to include linux/compiler.h from 
linux/comedidev.h - it should apply against comedi 0.7.69 okay.  You 
also need the attached compiler.h compatibility header.  It goes in 
Comedi's include/linux directory.
